5.37 FINAL DECISION: Determination of the Board, arrived at after consideration of the facts brought to its attention in accordance with 521 CMR.
5.38 FULL AND FAIR CASH VALUE OF THE BUILDING: The assessed valuation of a building (not including the land) as recorded in the Assessor's Office of the municipality at the time the building permit is issued as equalized at 100% valuation.
EXCEPTIONS:
a. If no assessed value exists, or the assessed value is more than three years old, a request to substitute the appraised value may be submitted to the Board. The request to use the appraised value must be submitted by a certified appraiser or for transit facilities, either a certified appraiser or an independent registered professional engineer and must be submitted prior to obtaining a building permit for the project.

c. The value of buildings owned, constructed, or renovated by the Commonwealth of Massachusetts shall be determined by the replacement cost.
The 100% equalized assessed value shall be based upon Massachusetts Department of Revenue's determination of the particular city's or town's assessment ratio.
EXAMPLE: Town X has an assessment ratio of 40%, the particular building in question is assessed at $200,000.00. To determine the equalized assessed value of this building, divide $200,000.00 by 0.4. The equalized assessed value equals $500,000.00.
When part of a building is subject to 521 CMR, the full and fair cash value shall be based on the percentage of the full and fair cash value of the whole which equals the ratio of the square footage of the part of the building to the square footage of the whole building; if the Board determines the application of this formula to cause an inequitable result, the Board may otherwise calculate the full and fair cash value of the part of a building at issue.
EXAMPLE: Where the whole building is 100,000 square feet, the part in question is 10,000 square feet, and the equalized value of the whole is $1,000,000.00, the full and fair cash value of the part is $100,000.00
